As previously stated, please update android's platform to have the same options as apple. I'd love to have the base list option.

can u guys add the base codes for android. the apple version has a few more options that are pretty important and we could definitely use it on the android side.

Loved the app on my iPhone. Wish it was the same on android. Could you update so they are the same. Been awhile since an update

Friend of mine showed me this app on iPhone. And the iPhone version has a lot more features. Needs updating before I can give it a good score.

This is DOPE for maintainers! Zulu times are extremely helpful for annotating times in the forms! Suggestion for a future update. If possible to be able to add fuel conversions from gallons to pounds when we can't read POL's hand writing on the fuel receipt 😂

This excellent app is valuable for Air Force aircraft maintainers since it combines all the common times, dates, and frequently needed info right into your phone. Already a hit on the iPhone, now it is available on Android.
